Title:
ARRANGEMENT FOR THE PRODUCTION OF STRUCTURED SUBSTRATES
Document Type and Number:
WIPO Patent Application WO/2012/059087
Kind Code:
A3
Abstract:
The invention relates to an arrangement for producing structured substrates. Said arrangement comprises a device for applying layer systems (1) including a device for applying liquid materials (2), in particular photopolymer solutions, to rotating substrates, a housing (6), a rotating holder (3) for the substrate to be coated, a feeder (13) for liquid materials to be applied, and a collection device (4) that includes multiple removal contraptions (5) for liquid materials that do not remain on the substrate. The housing (6) of the device for applying liquid materials (2) is filled with an inert gas, in particular dried, molecular nitrogen, noble gas, or a mixture thereof. The additional receptacles and conduits of the arrangement for producing structured substrates are gas-tight and are designed such that an inert molecular nitrogen or noble gas atmosphere is created above the liquid contents thereof. The collection device (4) has various collection zones (9) in which different liquid materials can be selectively collected and selectively removed via the associated removal contraption (5). Said design of the arrangement for producing structured substrates allows to improve the quality of the production process and significantly lower the cost of the process as the quantity of photopolymers and other liquid materials required for the production process can be drastically reduced.
